An embodiment relates to a dual lens driving apparatus including: a housing; a first bobbin disposed inside the housing; a second bobbin disposed inside the housing and positioned away from the first bobbin; a first coil disposed on the first bobbin; a second coil disposed on the second coil; a magnet disposed in the housing and positioned opposite from the first coil and second coil; a base disposed below the housing; a board disposed between the housing and the base and opposite from the magnet and including a circuit member having a third coil; and a supporting member movably supporting the housing with respect to the board. The third coil includes a first axial coil which is disposed in a first direction and a second axial coil which is disposed in a second direction different from the first direction. The first axial coil includes four first axial coil units which are positioned away from one another. The four first axial coil units are connected to one another. The second axial coil includes four second axial coil units which are positioned away from one another. The four second axial coil units are connected to one another.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The lens driving apparatus of claim 1, wherein the first extension part comprises a portion having a wider width as it extends toward the center of the upper elastic member.
3. The lens driving apparatus of claim 1, wherein one surface facing the first extension in the external part of the upper elastic member comprises at least one bent surface.
4. The lens driving apparatus of claim 1, wherein the damper disposed between the first extension part and the external part.
5. The lens driving apparatus of claim 1, wherein the upper elastic member comprises a second extension part extending from the external part to the corner side of the housing and connected to the coupling part.
7. The lens driving apparatus of claim 1, wherein the first extension part is connected to the second extension part through the coupling part.
8. The lens driving apparatus of claim 1, wherein a portion of a side surfaces of the external part that faces an inner surface of the first extension part comprises a shape corresponding to a shape of the inner surface of the first extension part.
9. The lens driving apparatus of claim 1, wherein an inner surface of the first extension part comprises a portion having a curvature.
